WT5BZ]Based on the relationship between cross section variety and resistance of sample, a new formula was put forward to calculate the instantaneous corrosion rate of aluminum alloy.
针对铝合金腐蚀平均速率与瞬时速率的差异,根据腐蚀过程中试样横截面的变化与欧姆电阻的对应关系,建立了新的腐蚀速率计算方法。
Five to ten times of rated current was loaded,instantaneous disconnection and closure of micro breaker can be detected by TDS3014B oscilloscope.
介绍了用TDS3014B示波器观察小型断路器的电压及电流的同步波形实例,在小型断路器中通以5倍及10倍的额定电流,通过TDS3014B示波器可观察到小型断路器的瞬时分断情况,并可同时测量每一相的分断电流及分断电压。
